Linus Torvalds 8fc984aedc A pile of x86 fixes:
- Prevent a memory leak in ioperm which was caused by the stupid
     assumption that the exit cleanup is always called for current, which is
     not the case when fork fails after taking a reference on the ioperm
     bitmap.
 
   - Fix an arithmething overflow in the DMA code on 32bit systems
 
   - Fill gaps in the xstate copy with defaults instead of leaving them
     uninitialized
 
   - Revert: o"Make __X32_SYSCALL_BIT be unsigned long" as it turned out
     that existing user space fails to build.
